Can we improve corn silage quality by applying foliar fungicide?

Francisco E. Contreras Govea, Ph.D

Corn for silage is one of the most important crops to feed the dairy and beef cattle. In the United States, on average, 2.492 millions of ha are harvested and ensiled (Ferraretto et al., 2018). Some of the advantage of corn over other forages are lower harvesting cost, high yield per area, and the possibility of harvesting either for grain or silage depending on the market price. In addition, corn for silage has high energy value and provides effective fiber to maintain rumen health. Therefore, any new technology or alternatives to improve the nutritive value of corn for silage is worth it.

Effect of corn silage fiber digestibility on dairy cow performance

Fernando Diaz

Digestible fiber is an important nutrient in corn silage fed to lactating dairy cows. A recent metanalysis published by Danish researchers reported that across studies (29 experiments and 96 diets), an increment of one percentage unit in the fiber digestibility of corn silage increased daily milk yield by 0.185 lb. per day and bodyweight gain by 12 g per day.
